  • Hair clip structure
    Patent number: 6378532
    Abstract: The present invention relates to an improved hair clip structure, mainly comprising a base plate which has an elastic middle bracket and an upper clipping plate at one end, and a elastic middle bracket and an upper clipping plate being coupled together the other end, and a first latching member and a second latching member being disposed at the position proximate to their coupling position, such that the curved surface at the middle section of the middle elastic bracket generates a more definite and significant curvature change by the fixing of the first latching member and the second latching member in position when the upper clipping plate and the base plate are clipped, and further prevents the hair clip from being fallen off.
